# Security Patterns
|
|
|
|
Scannable patterns for security code review. Each file has:
|
|
- **Rule** — what to do
|
|
- **Correct Pattern** — code that works (Python)
|
|
- **Incorrect Pattern** — common mistakes
|
|
- **Edge Cases** — gotchas
|
|
|
|
Based on OWASP Top 10:2025 and recent security research.
|
|
|
|
## Patterns
|
|
|
|
### Fundamentals
|
|
|
|
| File | Topic | OWASP 2025 |
|
|
|------|-------|------------|
|
|
| [secure-defaults.md](secure-defaults.md) | Fail closed, deny by default, defense in depth | A06 |
|
|
| [input-validation.md](input-validation.md) | Allowlist > blocklist, validate at boundaries | A03 |
|
|
| [credential-handling.md](credential-handling.md) | No hardcoded secrets, environment/secret manager | — |
|
|
| [audit-logging.md](audit-logging.md) | What to log, what not to log | A09 |
|
|
| [error-handling.md](error-handling.md) | Fail closed, no sensitive info in errors | A10 |
|
|
|
|
### Identity
|
|
|
|
| File | Topic | OWASP 2025 |
|
|
|------|-------|------------|
|
|
| [authentication.md](authentication.md) | Passwords, tokens, MFA, brute force protection | A07 |
|
|
| [authorization.md](authorization.md) | Permission checks, IDOR prevention, privilege escalation | A01 |
|
|
|
|
### Attack Prevention
|
|
|
|
| File | Topic | OWASP 2025 |
|
|
|------|-------|------------|
|
|
| [injection-prevention.md](injection-prevention.md) | SQL, command, template, path traversal | A05 |
|
|
| [dos-prevention.md](dos-prevention.md) | Rate limiting, resource bounds, algorithmic complexity | — |
|
|
| [prompt-injection.md](prompt-injection.md) | LLM security, data/instruction separation | — |
|
|
| [deserialization.md](deserialization.md) | Untrusted data deserialization, pickle, yaml | A08 |
|
|
|
|
### Infrastructure
|
|
|
|
| File | Topic | OWASP 2025 |
|
|
|------|-------|------------|
|
|
| [supply-chain.md](supply-chain.md) | SBOM, dependency scanning, signed packages | A03 |
|
|
| [cryptography.md](cryptography.md) | Strong algorithms, key management, TLS | A04 |
|
|
|
|
